What is plastic welding?

Plastic welding is a process of uniting surfaces of materials with the aid of heat (as opposed solvent welding or mechanically affixing). Welding of thermoplastics is accomplished in three sequential stages, namely surface preparation, application of heat and pressure, and cooling.

With speed tip welding, the plastic welder, similar to a soldering iron in appearance and wattage, is fitted with a feed tube for the plastic weld rod. The speed tip heats the plastic welding rod and the substrate, while at the same time presses the molten weld rod into position. A bead of softened plastic is laid into the joint, and the parts and weld rod fuse. The speed tip welding method is a fast welding technique and can be used in tight corners.
